There is a filter material today, called Berkey Fluoride Filter Aluminum, which is very useful for filtering water. This filter material is made by the method of fine research. The material is special, and it can remove all kinds of filth in the water. It is especially good at removing fluoride, so that the water is pure and free of impurities.

Looking at its structure, it is fine and subtle. There is an exquisite texture inside, just like mountains and rivers. Water passes through it, and impurities are like lost beasts, trapped in it. Its texture is tough. Although it has been immersed in water for a long time, it is not eroded. It is as solid as a rock, and it always maintains the ability to filter.
